Product Description

The Hassns Pro 7 hub is a sealed bearing hub designed for disc brake systems. It is praised for its high number of engagement points (often specified as 72 clicks with a 6-pawl system, some sources mention 120 engagement points depending on the specific model/batch) which provide quick and precise power transfer.

• Material: The hub body is made from high-strength 6061 aluminum alloy, while the freehub body (tower base) is often 7075 aluminum alloy.
• Bearings: It features a sealed bearing system for low maintenance, typically with two sealed bearings in the front hub and four in the rear hub.
• Braking System: It is designed specifically for use with disc brakes.
• Compatibility: The freehub body is compatible with Shimano HG (HyperGlide), SRAM XD, or Shimano MS (Micro Spline) cassettes, supporting 7 to 12 speed drivetrains.
• Sound: A notable characteristic is the distinct, loud ratchet sound (sometimes referred to as "noisy cube" or "120 sound") when coasting.
